Connecting to Your Database
Setting Additional Connection Parameters

To set AutoCommit and Lock (Isolation Level) in a database profile:

1. Display the Database Profiles dialog box.

2. Click the plus sign (+) to the left of the interface you are using.

   or

   Double-click the interface name.

   The list expands to display the database profiles defined for your interface.

3. Select the name of the profile you want and click Edit.

   The Database Profile Setup dialog box for the selected profile displays.

4. On the Connection tab page, supply values for one or both of the following:

   • Isolation Level

     If your database supports the use of locking and isolation levels, select the isolation level you want to use for this connection from the Isolation Level drop-down list. (The Isolation Level drop-down list contains valid lock values for your interface.)

   • AutoCommit Mode

     The setting of AutoCommit controls whether InfoMaker issues SQL statements outside (True) or inside (False) the scope of a transaction. If your database supports it, select the AutoCommit Mode check box to set AutoCommit to True or clear the AutoCommit Mode check box (the default) to set AutoCommit to False.

     For example, in addition to values for basic connection parameters (Server, Login ID, Password, and Database), the Connection tab page for the following SAP Adaptive Server Enterprise profile named Sales shows nondefault settings for Isolation Level and AutoCommit Mode.

5. Click OK to close the Database Profile Setup dialog box.

   InfoMaker saves your settings in the database profile entry in the registry.

1. Open the Database painter.
